The specific embodiment
Please consult simultaneously Fig. 5 a-5i.Fig. 5 a-5i represents respectively the schematic diagram of each layer structure of rete K1 of the present invention.Rete K1 comprises one first protective layer L1, intermediate layer LM and one second protective layer L1 '; Wherein, intermediate layer LM comprises a color layers LC, and color layers LC comprises a design layer L5, a metallic dielectric layer L6 and a coat of metal L7; In simple terms, rete K1 is the laminated body with first surface s01 and second surface s02.By first surface s01 on the direction of second surface s02; rete K1 has comprised following sandwich construction in order: the first protective layer L1, peel ply L2, ultraviolet ray (ultra-violet Rays, UV) layer L3, hyaline layer (clearlayer) L4, design layer L5, metallic dielectric layer L6, coat of metal L7, the second protective layer L1 ' and following layer L8.
Peel ply L2, ultraviolet ray layer L3, hyaline layer L4, design layer L5, metallic dielectric layer L6 and coat of metal L7 have consisted of intermediate layer LM; this intermediate layer LM is arranged between the first protective layer L1 and the second protective layer L1 '; and intermediate layer LM has comprised the color layers LC that is made of design layer L5 and coat of metal L7; this color layers LC has composition surface s07, and the second protective layer L1 ' is to be arranged at the composition surface s07 of color layers LC with respect to the first protective layer L1.Thus, in the technique manufacturing process, the second protective layer L1 ' can protect the color layers LC of intermediate layer LM in carrying out mould.
In present embodiment, ultraviolet ray layer L3 is protective layer, and hyaline layer L4 is dielectric layer, and coat of metal L7 is by being formed with sputtering way.In other embodiment, the coat of metal also can be substituted by the metal ink layer, and this metal ink layer is to form with mode of printing.It should be noted that, because the coat of metal or metal ink layer L7 are for being pre-formed among rete K1, so can obtain the uniform coat of metal or metal ink layer L7, can not cause the reduction of Electro Magnetic Compatibility (electromagnetic compatibility, EMC) (hereinafter to be referred as " EMC ") shielding benefit.
Please consult simultaneously Fig. 5 i, 6.The local making of schematic diagram when Fig. 6 represents to utilize making apparatus M to carry out to(for) rete K1 of the present invention.Rete K1 is applied to film interior trim (In-Mold Decoration, IMD) (for example: in-mold transfer printing (In-Mold Roller, IMR) or in-molded (In-Mold Forming, IMF) technique).
Making apparatus M comprises a plurality of coiler device m1, m2.Under the effect that moves back and forth with reel of coiler device m1, m2, the overlapped of each layer structure of rete K1 can sequentially be finished.When a plurality of coiler device m1, the m2 that utilize making apparatus M have finished peel ply L2, ultraviolet ray layer L3, hyaline layer L4, design layer L5, metallic dielectric layer L6 and coat of metal L7; that is; intermediate layer LM; making after, this moment with the second protective layer L1 ' to be arranged at the side of color layers LC with respect to the first protective layer L1.
Subsequently, shown in Fig. 5 i, following layer L8 is arranged at the side of the second protective layer L1 ', so so that the second protective layer L1 ' between the color layers LC and following layer L8 of intermediate layer LM.
In present embodiment; the first protective layer L1 is PETG (polyester, PET) layer, and the second protective layer L1 ' can by the material that is same as the first protective layer L1 (that is; PET) made, and also can be ultraviolet ray (UV) protective layer.In addition, the second protective layer L1 ' also can be and utilizes physical vapour deposition (PVD) (PhysicalVapor Deposition, PVD) or the formed layer of chemical vapour deposition (CVD) (Chemical Vapor Deposition, CVD) structure.
With regard to in-mold transfer printing (IMR) technique; the second protective layer L1 ' in rete K1 (can be the made layer structure of PET, PVD or CVD) can cover and the effect of protecting completely for its color layers LC; plastics material in the ejection formation process then can directly not cause the impact of color layers LC; and color layers LC can not be subject to the temperatures involved of the jet-out plastic material in the manufacturing process, so can avoid the generation of red ink phenomenon and can improve the yield of product.
In addition; because the coat of metal or metal ink layer L7 are between design layer L5 and in-mold transfer printing injection part; that is; the coat of metal or metal ink layer L7 can be subject to the pincer attack protection between design layer L5 and the in-mold transfer printing injection part; the coat of metal in rear operation or metal ink layer L7 are difficult for being damaged, and so can significantly promote the EMC shield effectiveness.With regard to in-molded (IMF) processing procedure, but the yield of Effective Raise product like this.
Fig. 7 is applied to the rete K2 of the second embodiment of the present invention of transfer printing rete K2 of inner mould transfer printing technology and the schematic diagram of each layer structure thereof.
By the structure of the transfer printing rete K2 among the regional z as can be known, transfer printing rete K2 has comprised the first protective layer L1, peel ply L2, ultraviolet ray layer L3, hyaline layer L4, design layer L5, metallic dielectric layer L6, metal level L7, the second protective layer L1 ' and following layer L8.
Fig. 8 a represents that transfer printing rete K2 is not bonded to housing H schematic diagram before, and Fig. 8 b represents that transfer printing rete K2 is bonded to housing schematic diagram afterwards.
Shown in 8a, 8b figure, a kind of casing of electronic apparatus made from inner mould transfer printing technology has comprised housing H and transfer printing rete K2.Housing H has surperficial h1.Transfer printing rete K2 is for being attached at the surperficial h1 of housing H by following layer L8, and the design layer L5 of transfer printing rete K2, metal level L7 directly do not contact with housing H.
Hence one can see that, design layer L5, the metal level L7 of transfer printing rete K2 directly do not contact with housing H and protective effect via the second protective layer L1 ' (pet layer) under, the design layer L5 in the structure of transfer printing rete K2 can be protected completely.Although the present invention discloses as above with preferred embodiment; yet it is not intended to limiting the invention; any those who are familiar with this art; without departing from the spirit and scope of the present invention; when can making all changes that is equal to or replacement, so protection scope of the present invention is when looking being as the criterion that claims define.
